File feels extremely slow and it doesn't seem to come with the sp to support it either. a +2 sp opening card would work better since you're starting Cath anyways, the level difference between a standard serpent to your deck causes the hick up when setting up the field. That 1 turn of delay is probably causing you to fall behind.

Hi! thank you everyone for your sugestions. Sorry if i make hard to understand what i say. English is not my first language. Also i just modified my decks following your instructions but i dont have a low level tank for the serpent file. Im not a free player but not a big espender either. More sugestions would be welcome and i will keep working on this. ( first time posting in a forum also)

This is a minor thing, but imo if you are running a file with level 4 units, just using 1 SP gen grim is sufficient, and 2 is excessive. If you think about it, the SP gen grim is paying for you to be able to go from 3 falkow to 4 falkow. Having a second SP gen is probably inefficient (the second mof isn't giving you necessary SP and also is prolly a waste of a set phase).
